Description

The invention relates to a rack server housing, which has a housing bottom and two opposite side walls.

Rack servers are known in the art, typically having a rack server enclosure. Inside the rack server enclosure are a variety of rack server components, such as hard drives, fans, circuit boards, and more. These components are surrounded by multiple walls of the rack server enclosure for protection. In the case of maintenance of the rack server, it is necessary to open it, which is typically done via a cover page. In order not to have to open the entire cover page in case of maintenance, the top wall is divided into several sub-elements. This does not necessarily mean that all subelements have to be removed in order to gain access to certain components, such as fans.

The US 2008/0 123 276 A1 relates to a sliding lid end wall and an electronic device with such a wall.

The DE 101 13 688 A1 relates to a housing, in particular for a computer, with a rack, with a cover part and with at least one sliding closure for fixing a wall of the lid part on the rack.

The DE 298 08 436 U1 relates to a housing for data processing equipment, in particular a housing for a designated as a tower or minitower personal computer.

The DE 10 2011 107 805 B4 relates to a mobile phone or laptop with a camera housing and a lid with which a lens of the camera can be covered or released.

An object underlying the present invention is to provide a rack server housing which contributes to cost-effective manufacture.

Disclosed is a rack server housing having a housing bottom and opposing side walls disposed thereon. The rack server housing has a first and a second cover element, each having at least one similar mounting recess in an edge region, wherein the first and second cover element are fixed to the side walls such that the two edge regions are at a distance from each other and the two mounting recesses point-symmetrical to each other are arranged. Furthermore, the rack server housing has a third cover element which can be inserted into the first and second cover element in such a way that in each case an engagement element of the cover element is arranged in a corresponding attachment recess and the third cover element from the first state into a second state both along a first direction and along a direction opposite to the first direction second direction is displaceable, so that the third cover element via the engagement elements enters into an at least positive connection with the first and the second cover element.

The cover elements form a common cover or a common cover element when the third cover element is positively connected to the first two cover elements. For example, the cover elements are substantially flush and form a common cover surface.

The mounting recesses and the engaging elements cooperating therewith are formed so that both displacement of an inserted third cover sheet in the first and second directions results in positive locking to the respective first and second cover members. In other words, the fastening recesses and the engagement elements are designed such that a displacement of the third cover element located in the first state away from or towards the first cover element (in contrast to the second cover element) in each case leads to a mechanical positive connection. The engagement elements thus interact mechanically in the region of the fastening recesses with the first and second cover element.

Optionally, the engagement elements and mounting recesses are formed such that in addition to the positive locking a frictional connection in the second state of the third cover element is achieved. This contributes to a secure mechanical fixing of the third lid member to the rack server housing.

This makes it possible to form the first and second cover element identical or identical at least in the edge region with the mounting recesses. As a result, for example, manufacturing costs can be reduced because about only one punching, embossing or molding tool for the edge region with the mounting recess is necessary. Furthermore, it is also possible to arrange the first and second cover element as desired interchanged, yet by means of the third cover element, a positive connection with both first and second cover elements can be produced. This contributes to structural flexibility. The first and second cover element are, for example, rotated by 180 ° relative to one another with respect to an axis of rotation which is normal to the housing bottom.

According to one embodiment, the edge regions of the first and second cover element have a bearing surface for the third cover element, on which the third cover element rests in the first state and on which the third cover element is moved to the second state, wherein the displacement takes place in a predetermined direction , The displacement of the third cover element preferably takes place parallel to the common cover surface. In other words, the displacement takes place parallel to a main extension plane of the third cover element, parallel to a direction of insertion of the rack server housing into a server rack. The direction is predetermined, for example, by geometric or constructive boundary conditions. Due to the given direction, shifting is only possible in one direction.

Preferably, the predetermined direction corresponds to a flow direction of an air flow generated by fans disposed in the rack server housing. This has the advantage that the displacement on the support surface leads to a greater overlap of the third cover element with the edge region of the cover element, which is arranged downstream in the flow direction. In other words, the overlap with the first or second lid member is increased depending on whether it is shifted toward the first or second lid member. This increased overlap has the advantage that an increased and / or mechanically improved seal against the air pressure generated by the fans can be achieved. Inadvertent release of the third cover plate can be avoided or at least prevented.

According to a further embodiment, the third cover element has at least one coupling element which engages in the first state in a slot-like recess which is formed so that it defines the predetermined direction for shifting to the second state. The slot-like recess corresponds to a geometric specification for enforcing the given direction. For example, the slot-like recess is formed in one or both side walls of the rack server housing. For example, a profile of the recess is L-shaped, so that the third cover element can be inserted into the recess in an insertion direction and subsequently displaced in the first or second direction. The insertion direction runs, for example, normal to the housing bottom. The coupling element is, for example, a pin, pin, bolt, a pin-shaped element or the like.

According to a further embodiment, the first and second cover element are configured identical. This makes it possible to design not only the two edge regions identical, but the entire cover element. As a result, not two different cover elements are necessary, but there must be only one cover element in twice the number. As a result, only a manufacturing process for a lid member is necessary. This contributes to a cost-effective production, since only for the one lid element, the corresponding tools and machines must be kept and the lid member can be produced in a higher number.

According to a further embodiment, the mounting recesses are each T-shaped and formed the engagement elements each as an L-shaped tab.

According to a further embodiment, the fastening recesses are each formed I-shaped and the engagement elements each formed U-shaped. In other words, the attachment recesses are "bone-like" and the engagement elements are "bridge-like".

The aforementioned embodiments of the fastening recesses and engagement elements make it possible to produce a positive connection with the third cover element, which can be reached in both the first and in the second direction.

According to a further embodiment, each engagement element in each case has a contact surface, which in the second state is in contact with the corresponding first or second housing cover, wherein the contact surface has a predetermined inclination with respect to a main extension plane of the third cover element. Due to the inclination, a clamping effect is achieved when moving the third cover element into the second state. As a result, the third cover element is fixed positively and non-positively to the first and second cover element.

According to a further embodiment, the third cover element can be arranged in a predetermined orientation between the first and second cover element. As a result, the third cover element between the first and second cover element can only be arranged in a specific orientation. In other words, the orientation of the third lid member is "coded". This can, for example, due to geometric constraints such as the above-mentioned coupling elements and by the slot-like recess can be achieved. This "coding" contributes to a simple and quick installation.

According to a further embodiment, the third housing cover is latched or locked in the second state and / or is secured in the second state by means of a fastening element. For example, a quick release is provided, so that the third cover element is mechanically secured in the second state. As fasteners offer, for example, glands or riveting.

According to a further embodiment, the third cover element is a fan cover. The fan cover, which may also be referred to as a fan cover, can thus be quickly removed or disassembled during operation in order to access one or more fans which are arranged in the rack server housing. It is not necessary to remove other covers, such as the first or second cover element.

Further advantageous embodiments are disclosed in the following detailed description of an embodiment.

As an embodiment will be described below with reference to the attached figures. Similar or identically acting elements are provided across the figures with the same reference numerals.

In the figures show:

1 shows a perspective view of a rack server housing 1 for a server rack. In the rack server enclosure 1 are several, unspecified components such as processors, hard drives or the like arranged or arranged. The rack server enclosure 1 is typically inserted into a rack together with its internally located components.

The rack server enclosure 1 has a housing bottom 2 as well as arranged, opposite side walls 3 on. On a rack server top 4 that the case bottom 2 is opposite, a plurality of cover elements are provided, which together form a common cover or a common cover. The rack server enclosure 1 has a first cover element 5 and a second lid member 6 , The two cover elements 5 . 6 are structurally identical and on the side walls 3 established. For example, the first cover elements 5 and 6 riveted to the side walls. The caseback 2 , the side walls 3 as well as the lid elements 5 . 6 are formed of metal sheets.

The first and second cover element 5 and 6 are a point symmetry axis 7 rotated by 180 ° and in a common plane 19 arranged horizontally offset. The level 19 corresponds to a main extension plane of the two cover elements 5 . 6 , The cover elements 5 . 6 define in the assembled state according to 1 a common lid surface 10 that are parallel to the plane 19 runs. Each of the two cover elements 5 and 6 has a border area 8th which runs essentially along one edge. The border area 8th is designed as a mounting area with a stepped tab and has a plurality of mounting recesses 9 on. The stepped tabs are with respect to the common lid surface 10 slightly inward towards the housing bottom 2 offset in parallel. The two border areas 8th have in the assembled or fixed state to each other. The two cover elements have 5 . 6 a first distance A1 to each other. The border areas 8th form a support surface for another, later to be described third cover element.

The area of the inside of the rack server enclosure 1 that is between the two lid elements 5 and 6 of the rack server chassis 1 is intended for the inclusion of multiple fans to form a fan bank. These can be in the rack server enclosure 1 be used or disassembled without, as in 1 shown the need exists, the cover elements 5 . 6 to decrease.

2 shows in perspective a third cover element 11 from a bottom, which between the first and second cover element 5 respectively 6 is used in this. For this purpose, the third cover element 11 on both sides several engagement elements 12 , which are formed as U-shaped tabs. The U-shaped tabs each define an opening 13 (see also 4 ).

3 shows an enlarged partial sectional view of the in 1 illustrated rack server enclosure 1 in which the three fastening recesses 9 are shown enlarged. The mounting recesses 9 are I-shaped (also referred to as double T-shape) in the border areas 8th the first and second cover element 5 . 6 brought in. They have a central region with a second distance A1 of two opposite edges and the middle region laterally each followed by an area with a third distance A3 of two opposite edges, which is larger than the second distance A2. The edges run parallel to the lid surface 10 and perpendicular to a direction of insertion 20 of the rack server chassis 1 (see arrow in 1 ). Due to the described shape, two inwardly facing webs arise 14 the lid elements 5 . 6 for each mounting recess 8th ,

Next is in 3 to recognize that sideways in each sidewall 3 two slot-like recesses 15 are introduced. The backdrop-like recesses 15 have an upwardly open, L-shaped course. Corresponding to this, as in 2 illustrated, the third cover element 11 on opposite side flaps two projections 16 representing coupling elements. The projections 16 are pin-shaped, such as a bolt, and have a cylindrical shape (s. 4 ). The backdrop-like recesses 15 offer at least partially a forced operation, especially two-sided forced operation, for the projections 16 ,

The third cover sheet 11 , which may also be referred to as fan cover sheet, is mounted such that it is in a first mounting direction 21 in the first and second cover element 5 . 6 is used (s. 2 ). In doing so, the engagement elements appear 12 through the mounting recesses 9 and the projections 16 grab into the slot-like recesses 15 one. Because of the projections 16 and the slot-like recess 15 can the cover element 11 only in a certain orientation between the two first and second cover elements 5 and 6 be used.

This first mounting state is in 5 shown. It should be noted that the rack server enclosure 1 in 5 180 ° opposite 1 is twisted. In this state, close the first, second and third cover element 5 . 6 and 11 flush so that they are the common lid surface 10 form.

Subsequently, the third cover element 11 in a predetermined second mounting direction 22 , due to the geometric conditions of the sliding recesses 15 is forced and the insertion direction 20 corresponds, in the direction of the second cover element 6 postponed. The engagement elements encompass this 12 one each of the two bars 14 the mounting recesses 8th the first and second cover element 5 . 6 ,

Due to the predetermined direction, the third cover element moves 11 from the first lid member 5 away and on the second cover element 6 to. Due to the fact that the mounting recesses 8th are point-symmetrical and identical, is about each engagement element 12 a positive connection with the first and second cover element 5 respectively 6 reached. In other words, the mounting recesses 8th and the corresponding engagement elements 12 designed so that it is equal to which direction of displacement of the third cover element 11 both with the first and with the second cover element 5 . 6 comes to a positive conclusion. So it would be conceivable, for example, that the backdrop-like recesses 15 , in particular parallel to the insertion direction 20 extending section, facing in the other direction and the cover element 11 in the direction of the first cover element 5 could be shifted, wherein the predetermined direction opposite to the insertion direction 20 is.

This second mounting state is in 6 and 7 shown in a perspective and a cross-sectional view. It can be seen that the engagement elements 12 the footbridges 14 and thus the first and second cover element 5 and 6 engages behind. This is done with the first and second cover element 5 . 6 the positive connection reached.

Additionally is in 6 and 7 to recognize that a middle web section 17 of each engaging element 12 an internal contact surface 18 has, which is tilted. Due to the inclined contact surface 18 a clamping effect is achieved, so that the third cover element 11 not only form-fitting, but also non-positively on the first and second cover element 5 . 6 is fixed.

The direction of displacement of the third cover element 11 from the first to the second state is selected to correspond to an air flow direction of the in the rack server housing 1 arranged fans would be generated. This has the advantage of being the edge area 8th the second cover element 6 , in the direction of which the third cover element 11 is moved, experiences a greater overlap than the edge area 8th of the first lid member 5 of which the third cover element 11 moved away. Due to this overlap, openings become in the region of the overlap with the second cover element 6 avoided or at least reduced. This contributes to a seal on the side of the fans that is exposed to increased air pressure due to the fans.

Furthermore, based on 5 to realize that the lid elements 5 . 6 , and 11 are formed so that after moving the third cover element 11 according to the second mounting direction 22 no openings such as mounting holes or parts of the mounting recesses 9 at least partially open. This avoids undesirable effects such as flow restrictions for the fans or the like. In other words, preparations are in the adjacent parts of the three lid members 5 . 6 , and 11 met, which are reusable by the symmetry.

Optionally, the third cover element 11 be secured by additional fastening measures such as riveting, screwing, locking or the like and / or by quick-release mechanisms.

The described embodiment allows the advantages and functions mentioned above, in particular a cost-effective production of the rack server housing 1 is possible. Due to the fact that the first and second cover element 5 . 6 identical or at least in the peripheral areas 8th is designed to be identical, the manufacturing process is simplified and can be more cost-effective compared to different cover elements 5 . 6 fail. The third cover element 11 is easy to handle in this symmetrical structure and it will be the available volume and possible directions of movement for fixing the third cover element 11 optimally utilized. It should be noted that the configuration of the mutually correspondingly cooperating engagement elements 12 and mounting recesses 9 may also be configured differently, to a positive and / or adhesion in two displacement directions of the third cover element 11 to effect. For example, the engagement elements 12 L-shaped and the mounting recesses 9 T-shaped design, which remains essentially unchanged on the operating principle. Another alternative is the engagement elements 12 designed as a T-bolt formed in elongated hole mounting recesses 9 engage, with the slots parallel to the insertion direction 20 extend. For example, a clamping effect can be achieved in the second state of the third cover element 11 in that the elongated holes taper in the direction of their opposite ends, and so the bolts are jammed.
